Abstract
The chemical and fatty acid composition were evaluated of commercially important fish species (common carp, silver carp, bighead carp, grass carp, Wels catfish, and zander) which were collected from retail stores in the area of Novi Sad, Republic of Serbia. The amount of protein was the highest in zander (19.27%) and the lowest in grass carp fillets (14.73%). The percentage of fat ranged from 1.8 in zander to 10.07 in common carp. The total cholesterol content was the highest in Chinese carps fillets (approximately 65.38 mg/100 g), and the lowest in Wels catfish (33.14 mg/100 g). SFA were lowest in zander (28.6%). Bighead carp meat contained the highest percentage of PUFA (33.73%) while the lowest percentage was detected in common carp (20.1%). The chemical and fatty acid compositions of fish vary greatly between different species and within the same species. The quality of fish meat in Serbian retail stores is quite good but it should be improved by using feed mixtures on fish ponds.
